Answer:
cos(E)=0.8
Step-by-step explanation:
cos(E)=adjacent/hypotenuse
Using a common pythagorean triple, we can find that side GE is 30 (18^2+24^2=30^2)
Then we just get cos(E)=24/30, which is 0.8
Answer:
16m+1
Step-by-step explanation:
Knowing about our proprieties about parentheses and negatives, let's solve this out.
<u>A negative multiplied by a negative give you a positive</u>
therefore....
-(-16m-1)= 16m+1
The -1 also receives the negative because the problem was in a parentheses :)
